Table IV.

Relationships between the measured volumetric wear rates of the taper surfaces and the examined variables. Results are shown as Spearman’s rank correlations with p-values in parentheses. Significant results are in bold

	Articuleze (n = 48)		ASR* XL (n = 63)
Surface wear	-0.236 (p = 0.136)		0.003 (p = 0.982)
Bearing diameter	-		0.150 (p = 0.249)
Taper angle	0.235 (p = 0.108)		0.383 (p = 0.002)
Head offset	0.323 (p = 0.027)		0.278 (p = 0.091)
Distance (taper engagement level to centre of rotation)	0.321 (p = 0.034)		0.363 (p = 0.006)
Horizontal lever arm distance	0.408 (p = 0.008)		0.380 (p = 0.004)
